　　As a manufacturer of ventilation pipes, all we can do is to do a good job of ventilation pipes, so that the building can obtain a reliable ventilation system in use. The quality of our products may bring changes to your life, as well as more safety factors. What are the advantages of the ventilation pipes produced by Jinan ventilation equipment factory?

　　1. The simple construction of ventilation pipe can greatly improve the indoor environment by increasing the indoor space, airtight, no smoke, no smell.

　　2. 造價低:與傳統(tǒng)磚砌通風管道相比，可節(jié)省約40%的工程造價;

　　2. Low cost: compared with the traditional brick ventilation pipe, it can save about 40% of the project cost;

　　3.重量輕、強度高:與傳統(tǒng)磚通風機相比，菱鎂礦通風機重量輕、強度高，可大大減輕建筑物的負荷;

　　3. Light weight and high strength: compared with the traditional brick ventilator, the magnesite ventilator is light weight and high strength, which can greatly reduce the load of buildings;

　　4. 獨特的設計:通風管道的開口處設有防煙止回閥和防火隔離門，有效防止異味和火災。

　　4. Unique design: anti smoke check valve and fire isolation door are set at the opening of ventilation pipe to effectively prevent peculiar smell and fire.

　　6. Good fire performance of ventilation duct: at present, the common problem is that the combustion performance and fire resistance limit of the finished ventilation duct have not been tested by relevant national departments, and the combustion performance and wall thickness of some ventilation ducts do not meet the requirements.
